FEL TEMP REPARATIO: The Roman Centenionalis Coinage

Illustrated Specimen Details: Roman Bronze Centenionalis

Example Specimen: Centenionalis, 361-363 (Later Roman Empire)

Authority & Identification: This ancient bronze coin is a classic centenionalis issued by the Later Roman Empire. It was struck without a specific date during the reign of Julian II, famously known as Julian the Apostate due to his promotion of Neoplatonic Hellenism over Christianity, who ruled from 361-363 AD. The obverse features a detailed portrait of the emperor accompanied by the Latin inscription "D N IVLIANVS NOB CAES", which translates to "Our Lord Julian, the noble Caesar", along with an unidentified "M" mint mark on the left side. The reverse displays a dynamic military scene of a Roman warrior spearing a fallen barbarian horseman, encircled by the famous propaganda legend "FEL TEMP REPARATIO", meaning "Restoration of happy times". This specific piece was produced at the ancient mint of Aquileia in modern Italy.

1. ROMAN EMPIRE (350-400): centenionalis

CENTENIONALIS as a coin name. The centenionalis is widely regarded as one of the most ambiguous coin denominations in ancient Roman numismatics. In traditional literature, this term confidently describes a series of small bronze coins issued by the Later Roman Empire during the second half of the 4th century AD. However, modern identification often yields conflicting expert opinions, with identical specimens frequently classified interchangeably as a centenionalis, a maiorina, a follis, or simply assigned a generic AE grade. Historical evidence suggests that by the middle of the 4th century, the heavily depreciated follis could no longer facilitate reliable everyday trade. Around 350 AD, two new bronze or copper coins were introduced to restore public confidence. Modern numismatists typically designate the smaller coin, weighing up to 3 grams, as the centenionalis, while the larger 5-gram piece is known as the maiorina. Standard catalogs predominantly feature the centenionalis strictly within the 350-400 timeframe.

History and Classification of the Roman Centenionalis

Late Roman Monetary Reforms

The centenionalis emerged as a crucial component of the small bronze denominations created during the extensive monetary reforms of the 4th century AD. During this tumultuous period, the Roman currency system underwent repeated reorganizations to combat severe inflation and political instability. The denomination is most closely associated with the reigns of prominent emperors such as Constans, Constantius II, Julian, Valentinian I, and Theodosius I. While the gold solidus dominated high-value state transactions, these small bronze issues were minted in massive quantities to serve the everyday retail trade and sustain local urban markets across the vast, geographically diverse empire.

Physical Characteristics and Propaganda Imagery

Struck primarily in bronze or various copper alloys, these coins typically feature a compact size ranging from 15 to 22 millimeters and highly variable weights generally falling between 1.5 and 3.5 grams. The obverse designs consistently present a stylized, diademed, or helmeted portrait of the reigning emperor. The reverse sides were utilized as powerful tools for imperial propaganda, displaying triumphant themes such as the goddess Victoria, soldiers holding military standards, the personification of Roma seated, or the emperor violently dragging a captive barbarian. Many issues also prominently feature Vota inscriptions, publicly celebrating the emperor's vows and continued years in power.

The Etymological Debate and Modern Cataloging

The term centenionalis itself is largely a modern numismatic convention rather than a strictly documented ancient Roman classification. Scholars hypothesize that the name might derive from a theoretical economic value related to a hundred units, though its exact contemporary meaning remains a subject of intense academic debate. Because the true ancient nomenclature is lost to history, modern collectors and standard numismatic catalogs often categorize these artifacts not by name, but by their physical dimensions using the AE2, AE3, or AE4 bronze classification systems. Despite this historical ambiguity, the coin remains an essential and highly collectible artifact representing the twilight economy of the classical Roman world.
